Objective: This study aimed to evaluate the effects of a digital group reminiscence program on elderly patients with mild dementia who were registered with Day Care Centers. Methods: The study was conducted with elderly patients with mild dementia in Day Care Centers in D city. The patients were randomly assigned to either the experimental group or the control group and were assessed for cognitive function, depression, and ego integrity using pre-test and post-test designs. A digital group reminiscence program was applied to the experimental group. Data was collected from July 5 to September 17, 2021, using questionnaires in three sessions. Results: The pre-test cognitive function score was 12.00 in the experimental group and 11.09 in the control group. The post-test cognitive function score was 19.20 in the experimental group and 14.42 in the control group. The later cognitive function score was 18.00 in the experimental group and 13.31 in the control group. The pre-test depression score was 8.32 in the experimental group and 9.91 in the control group. The post-test depression score was 6.05 in the experimental group and 8.82 in the control group. The later depression score was 6.94 in the experimental group and 9.02 in the control group. The pre-test ego integrity score was 41.39 in the experimental group and 39.55 in the control group. The post-test ego integrity score was 57.95 in the experimental group and 51.41 in the control group. The later ego integrity score was 55.88 in the experimental group and 42.15 in the control group. Cognitive function, depression, and ego integrity showed significant differences according to group (p<.05), time (p<.001), and interaction between group and time (p<.01). Conclusion: The digital group reminiscence program was found to be effective in improving cognitive function and ego integrity and reducing depression in elderly patients with mild dementia. Further research is needed to explore the effects of repetitive digital group recall programs based on the progress, course, age, and communication level of dementia.

In order to assess the correlation of the myocardial damage and the duration of cardiopulmonary bypass, measurement of creatine kinase [CK], lactate dehydrogenase [LDH], asparatate aminotransferase [AST], and MB band of CK [CK-MB] were carried out on the first, third, fifth, seventh, and ninth day in 44 patients following open heart surgery [POD 1,3,5,7,9]. And the patients were divided into three groups according to the duration of aortic cross clamp time [ACT]: Group I [ACT< 60 minutes. n=19], Group II [60 minutes < ACT< 90 minutes, n=7] and Group III[90 minutes > ACT, n=18]. 1. The leakage of CK in total patients increased to the highest level at POD 1, with rapid decrease and recovery at POD 7. The leakage of CK in Group III were greater than in Group I from POD 1 to POD 3 [P < 0.01]. The recovery time of CK level was shorter in Group I [POD 3] than in Group II and III [POD 7]. 2. The serum levels of LDH in total patients increased to the highest level at POD 1, with slow recovery until POD 9. The levels of LDH in Group III were higher than in Group I until POD 9 [P < 0.005]. The levels of LDH in Group I and II recovered but not in Group III. 3. The serum levels of AST in total patients increased to the highest level at POD 1, with rapid decrease and recovery at POD 7. The levels of AST in Group III were greater than in Group I from POD 1 to POD 5 [P < 0.05]. The recovery time of AST level was shorter in Group I and II [POD 5] than in Group III [POD 7]. 4. The positive cases for CK-MB in 36 patients were 22 [61.1 %] as a whole, 5[41.6%] in Group I, 4[57.1 %] in Group II, 13[76.4 %] in Group III at POD 1, and a case in each group at POD 3, and only a case in Group Ill at POD 5. It is concluded that the myocardial injury was closely related with the duration of cardiopulmonary bypass in open heart surgery.

Protective effect of superoxide dismutase[SOD] and substrates on acute ischemic and reperfused myocardium was assessed by cardiac microdialysis. 30 Rabbits were divided into 4 groups; normal control group [group I, n=5], ischemic group [group II, n=5], SOD treated group [group III, n=10], and substrates treated group [group IV, n=10]. After a microdialysis apparatus was implanted in rabbit myocardium, coronary artery was occuluded for 5 minutes and reperfusion was performed for 30 minutes. Hemodynamic changes, CK-MB isoenzyme level and adenine ring compound level in effluent dialysates [equilibrated with interstitial fluid], and ultrastructural changes of myocardial cell were analysed. Systolic blood pressure at 10 and 30 minutes after reperfusion was higher in group III and IV than in group II [p<.05]. Also percent recovery of systolic blood pressure in group III [p<.01] and IV [p<.02] was higher than in group II. CK-MB isoenzyme level in effluent dialysates was peaked at 10 minutes after reperfusion, thereafter decreased in group II, III and IV. At 30 minutes after reperfusion, its level was lower in group III and IV than in group II[p<.05]. Adenine ring compound level in effluent dialysates increased till 10 minutes after reperfusion and progressively decreased. At 10 and 30 minutes after reperfusion, its level was lower in group III and IV than in group II without significance. Degree of myocardial damage was estimated by scoring of mitochondrial injury. Group I was within normal range and most severe injury was seen in group II. And the score of mitochondrial injury in group III and IV was lower than in group II. In conclusion, SOD and substrates[KMP solution] had protective effect on stunned myocardium. The microdialysis appratus was a good device for studying stunned myocardium, and cardiac microdialysis might be a unique technique for analysis of regional intramyocardial interstitial fluid.

To investigate effects of Paeonia Radix Rubra aqua-acupuncture on Adjuvant Athritis in rats, the edema rate, the number of WBC, the quantity of total protein, albumin and globuline in the blood serum were measured and histological test of the muscular tissue were done in the arthritis part. 1. After arthritis of Sprague dawley(SD) rats was induced by injecting Freund's complete adjuvant for 2 weeks, normal saline was injected for the Control group and Paeonia Radix Rubra acua-acupuncture was injected for the Exp. group during 30 days. Selected point was $D{\acute{u}}bf(ST_{35})$ in both groups. And then the inframmator volume of plantar were checked. The volume of the plantar was $0.84{\pm}0.14mm$ in Control group and $0.57{\pm}0.09mm$ in Exp. group, the swelling of plantar was restricted significanily in Exp, group(P<0.05). 2. The number of WBC was $10.34{\pm}0.14(10^3/ml)$ in normal group and $37.47{\pm}5.46(10^3/ml)$ in Control group. It was $25.21{\pm}3.45(10^3/ml)$ in Exp. group. This fact showed that Exp group. with Paeonia Radix Rubra acua-acupuncture was more effective than Control group in the treatment of arthritis(P<0.05). 3. The content of total protein in the blood serum were $6.14{\pm}0.43g/d{\ell}$ in normal group, $7.95{\pm}0.94g/d{\ell}$ in Control group, and $6.82{\pm}1.23g/d{\ell}$ in Exp. group. There was no significance in total protein between Exp. group and Control group from the statistical analysis. 4. The contents of albumin in the blood serum were $2.94{\pm}0.13g/d{\ell}$ in normal group, $2.01{\pm}0.48g/d{\ell}$ in Control group and $2.75{\pm}0.14g/d{\ell}$ in Exp, group. This fact showed that Exp. group had significant increase in the serum albumin from the statistical analysis, in comparison with Control group(P<0.05). 5. The contents of globulin in the blood serum were $3.19{\pm}0.48g/d{\ell}$ in normal group, $4.70{\pm}1.26g/d{\ell}$ in Control group and $3.58{\pm}0.73g/d{\ell}$ in Exp. group. There was no significance in the serum globulin between Exp. group and Control group from the statistical analysis. 6. In histological examinadon, because inflammatory reaction was active, remarkably irregular tissue and large amount of inflammatory cells were found in Control. group. But Exp. group showed that tissues were in some degree recovered, the number of inflamed cells was decreased and inflammation was restrained. From these results, it is shown Paeonia Radix Rubra aqua-acupuncture restrained inflammatory reaction and muscular tissue necrosis in SD rat's plantar was restrained by Freund's complete adjuvant.

The purpose of this study was to observe the effects of far-infrared on rheumatoid arthritis induced rats by type ⅡI collagen with the change of arthritis index, hind paw volume, TNF-α and histopathologic findings. Thirty-six Sprauge-Dawley rats which were divided into four group. Group Ⅰ : Normal group, Group Ⅱ : Collagen-Induced Arthritis group, Group Ⅲ : Far-Infrared 25㎝ radiation group, Group Ⅳ : Far-Infrared 35㎝ radiation group. The results of this study were as follows: In arthritis index, far-infrared radiation group(Ⅲ, Ⅳ) are more decreased than collagen-induced arthritis group(Ⅱ). Group Ⅲ and Ⅳ showed the most significant effect at 14 day(p<0.05). In hind paw, far-infrared 25㎝ radiation group(Ⅲ) significantly decreased more than only collagen-induced arthritis group on day 14(p<0.05). Far-infrared 35㎝ radiation group(Ⅳ) significantly decreased more than collagen-induced arthritis group on day 3, 7 and 14(p<0.05). In the ELISA study of TNF-α concentration, collagen-induced arthritis group significantly increased in the concentration more than normal group. Far-infrared radiation group(Ⅲ, Ⅳ) decreased in TNF-α concentration more than collagen-induced arthritis group(Ⅱ) on day 14. In histopathologic findings, collagen-induced arthritis(Ⅱ) and far-infrared 25㎝ radiation group(Ⅲ) increased in synovial membrane thickness on 3 day. Far-infrared 35 em radiation group(Ⅳ) decreased in the concentration more than collagen-induced arthritis group on day 14. The above results suggest that far-infrared radiation effectively reduced in rheumatoid arthritis. It would be considered that far-infrared has an effects on relieving rheumatoid arthritis.
